Skin Barrier Strengthening

PHAs strengthen the skin barrier by promoting ceramide synthesis. This enhances skin hydration and protection against external irritants.

PHAs, specifically gluconolactone, enhance skin barrier function by stimulating ceramide synthesis. Ceramides are essential lipids that fill the spaces between skin cells, creating a protective barrier against water loss and external irritants. By increasing ceramide production, PHAs strengthen the skin's natural defense mechanisms, improving hydration and reducing sensitivity to environmental stressors.
